This statement is correct. All radioisotopes decay at separate rates. They are unique and are not altered by chemical compounds.

How do radioisotopes of an element differ feom other isotopes?

Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.


What are two types of radioactive decay?

The two types of radioactive decay are alpha and beta. Generally, in alpha decay the nucleus will lose 2 protons and 2 neutrons (it's a helium nucleus). Beta decay involves a neutron losing an electron and becoming a proton, so the atomic mass remains the same, but the atomic number increases by one since there is another proton.


What actually decays in radioactive decay?

The nucleus of the atom decays, and in the process, the nucleus transforms into another element, or into an isotope or isomer of the same element. In radioactive decay, the nucleus always emits some kind of particle(s). It is the high-energy emission of these particles that we call radiation. There are many different types of radioactive decay:Alpha decay results in the emission of an alpha particle (two neutrons and two protons)Beta decay results in the emission of a beta particle (an electron or a positron)Neutron decay results in the emission of a neutronProton decay results in the emission of a protonGamma decay results in the emission of a gamma particle (a photon)Neutrino decay results in the emission of a neutrino or antineutrinoIn some cases, a combination of the above emissions takes place. For example in double beta decay, a single nucleus emits two electrons and two antineutrinos in the same event.


What is rate when two reactions are in balance?

When the rate of the forward and reverse reaction is the same, the system is at equilbirium.


Alpha and beta decay emit what?

Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).


Which two elements undergo alpha decay?

The two elements that undergo alpha decay are uranium and thorium.


What are two uses of radioisotypes?

Radiometric dating is a common use of radioisotopes to determine the age of rocks, fossils, and archaeological artifacts. Radioisotopes are also used in medicine, such as in imaging techniques like PET scans and in cancer therapy.

How does the mass of a nucleus change with alpha decay?

When an atomundergoesalpha decay, it loses two neutrons (as well as two protons).
